A...waste of solar....internal ICE hydrogen motors is what these would be used for not fuel cell hydrogen.
How are you wasting solar? Lol this makes no sense. These can be stood up anywhere, you cannot use these as super chargers for batteries....
Because you can put that electricity directly into the grid rather than wasting it making hydrogen.
Lol that's not the goal, the goal is to charge a car... you're finding a problem to solve that's not even in the same area...
You can use electricity on the grid to charge a car. Not sure if you were aware of that. It's going to be a whole lot more efficient at it than hydrogen.
No shit. You know you need a substation to power a supercharger grid...you know how many substations just randomly exist in rural areas to power superchargers? And how expensive they are to build and maintain?
And hydrogen won't get you there. It's much easier to build a substation than the new infrastructure for hydrogen.
Lol no it is not, do you know what goes into building a substation? They're expensive and require a lot of upkeep.
And so does your idea; you just haven't thought it through.
A solar hydrogen station cost no where near the amount putting in a substation does. I don't even know where you came up with the idea that it does.
Dude, you don't even have a good grasp of how much hydrogen you could make from the atmosphere. Nobody is advocating for doing it that way because it's too much effort for so little gain. I'm not going to take your word on much else.

Yep, totally no one is doing it.... it's not being researched or anything, cause it's not worth it. Yep, miles and miles of over head wires and substations all over the place it the way to go. No other alternative.
There are very few details on how much they've actually generated on any of these. The MIT one doesn't specify how it's getting the original water at all.
The IEEE one does actually list it out:
Yeah, that's about what I'd expect. You are not going to power cars with this.
The one in the Guardian article seems to be targeting it a as a replacement for natural gas in home heating and cooking, which is a maybe.
Look at the efficiency of the energy conversions. It is literally wasting solar.
How is it wasted if it completely free energy? You cannot charge up electric cars quickly via solar....hell solar in general isn't super efficient anyways lol
No energy is free because there is always installation and maintance cost. Lot's of people change their cars off solar. Most of a car's life is sat parked for hours. So slow is fine. My charger has a solar divert function I'm yet to get the solar for. Also, you change a house battery slow and then a car fast from it. Even here in the UK there are people doing it. Not solar all the time, but a lot in summer. House battery changed when your in the office, car overnight from that.
